I understand and will do.

I am trying to understand why/how the old address was used when it did not appear to exist in the database at the exact time the order was placed, but was transmitted to PayPal. Changes to account info don't require a logoff/logon before being considered valid, do they?

That was one of the more recent changes for the OPC/PayPal integration, specifically forcing PayPal to bypass its 'create address' path when a new address (i.e. that stored at PayPal) was sent down.
